BACKGROUND OF THE INVENTION

Immunoregulatory abnormalities have been shown to exist in a wide variety of "autoimmune" and chronic inflammatory diseases, including systemic lupus erythematosis, chronic rheumatoid arthritis, type 1 diabetes mellitus, type 2 adult onset diabetes, inflammatory bowel disease, biliary cirrhosis, uveitis, multiple sclerosis and other disorders such as Crohn's disease, ulcerative colitis, bullous pemphigoid, sarcoidosis, psoriasis, ichthyosis, and Graves ophthalmopathy. Although the underlying pathogenesis of each of these conditions may be quite different, they have in common the appearance of a variety of autoantibodies and self-reactive lymphocytes. Such self-reactivity may be due, in part, to a loss of the homeostatic controls under which the normal immune system operates.

Similarly, following a bone-marrow or an organ transplantation, the host lymphocytes recognize the foreign tissue antigens and begin to produce antibodies which lead to graft rejection.

One end result of an autoimmune or a rejection process is tissue destruction caused by inflammatory cells and the mediators they release. Antiinflammatory agents such as NSAID's and corticosteroids act principally by blocking the effect or secretion of these mediators but do nothing to modify the immunologic basis of the disease. On the other hand, cytotoxic agents such as cyclophosphamide, act in such a nonspecific fashion that both the normal and autoimmune responses are shut off. Indeed, patients treated with such nonspecific immunosuppressive agents are as likely to succumb from infection as they are from their autoimmune disease.

Cyclosporin A which was approved by the US FDA in 1983 is currently the leading drug used to prevent rejection of transplanted organs. The drug acts by inhibiting the body's immune system from mobilizing its vast arsenal of natural protecting agents to reject the transplant's foreign protein. Though cyclosporin A is effective in fighting transplant rejection, it is nephrotoxic and is known to cause several undesirable side effects including kidney failure, abnormal liver function and gastrointestinal discomfort.

Newer, safer drugs exhibiting less side effects are constantly being searched for in the field.

The 23-membered tricyclo-macrolide immunosuppressant, tacrolimus, FR-900506, FK-506, ##STR3## (17-allyl-1,14-dihydroxy-12-[2'-(4"-hydroxy-3"-methoxycyclohexyl)-1'-methylvinyl]-23,25-dimethoxy-13,19,21,27-tetramethyl-11,28-dioxa-4-azatricyclo-[22.3.10⁴,9 ]-octacos-18-ene-2,3,10,16-tetraone) and related compounds which were isolated and characterized by Tanaka, Kuroda, and co-workers at Fujisawa Pharmaceutical Co. in Japan, see J. Am. Chem. Soc., 1987, 109, 5031, and U.S. Pat. No. 4,894.366, issued Jan. 16, 1990) have been shown to possess exceptional immunosuppressive activity. Fujisawa United States patents (U.S. Pat. No.4,929,611, issued May 29, 1990 and U.S. Pat. No.4,956,352, issued Sep. 11, 1990) disclose the use of FK-506-type compounds in treating resistance to transplantation. In particular, the compound FR-900506 has been reported to be 100 times more effective than cyclosporin in the supression of in vitro immune systems (J. Antibiotics 1987, 40, 1256). In addition, these compounds are reputed to possess topical activity in the treatment of inflammatory and hyperproliferative skin diseases and cutaneous manifestations of immunologically-mediated illnesses (EPO Pub. No. 0,315,978).

The compound FK-506 and related compounds further have been suggested to be useful in the treatment of obstructive airways disease, particularly asthma (PCT Publication WO 90/14826), male pattern alopecia or alopecia senilis (EPO Publication No. 0,423,714), rheumatoid arthitis (C. Arita, et al., Clinical exp. Immunol., 1990, 82, 456-461; N. Inamura, et al., Clin. Immunol. Immunopathol. 1988, 46, 82-90), recent-onset diabetes (N. Murase, et al., Diabetes, 1990, 39, 1584-86; N. Murase, et al., Lancet, 1990, 336, 373-74), posterior uveitis (H. Kawashima, Invest. Ophthalmol. Vis. Sci., 1988, 29, 1265-71), hepatic injury associated with ischemia (M. Sakr, et al., Life Sci., 1990, 47, 687-91) allergic encephalomyelitis (K, Deguchi, et al., Brain Nerve, 1990, 42, 391-97), glomerulonephritis (J. McCauley, et al., Lancet, 1990, 335,674), systemic lupus erythematosus (K. Takabayashi, et al., Clin. Immunol. Immunopathol., 1989, 51, 110-117) multidrug resistance (M. Naito, et al., Cancer Chemother. Pharmacol., 1992, 29, 195-200), inflammation of mucosa and blood vessels (PCT Publication WO 92/17754), cytomegalovirus infection (UK Publication GB 2,247,620A), and idiopathic thrombocytopenic purpura and Basedow's disease (PCT Publication WO 91/19495).

Soc., 1987, 109, 5031; J. Antibiotics, 1987, 40, 1249, J. Antibiotics, 1988, 41(11), 1592; and J. Antibiotics, 1992, 45(1), 118). Both biological fermentation and synthetic processes may be found. A synthetic route to compounds of Formula II can involve modifications of a route described in J. Am. Chem. Soc., 1989, 111, 1157.

Biological fermentation followed by synthetic modification is presently favored in the an as the method to produce compounds of Formula II. Organisms belonging to the genus Streptomyces such as Streptomyces tsukubaensis, No. 9993 and Streptomyces hygroscopicus, var. ascomycetis, No. 14891 placed in an aqueous nutrient medium will produce desired compounds in isolable amounts. The nutrient medium contains sources of assimilable carbon and nitrogen, preferably under aerobic conditions. Produced in fermentation are four compounds of Formula II, (A) where R² is methyl, W is O, R³ is hydroxyl, R⁴ is hydrogen, R⁵ is allyl and n is 2; (B) where R² is methyl, W is O, R³ is hydroxyl, R⁴ is hydrogen, R⁵ is ethyl and n is 2; (C) where R² is methyl, W is O, R³ is hydroxyl, R⁴ is hydrogen, R⁵ is methyl and n is 2; and (D) where R² is methyl, W is O, R³ is hydroxyl, R⁴ is hydrogen, R⁵ is allyl and n is 1.

A lyophilized sample of the isolated Streptomyces tsukubaensis, No. 9993 was deposited with the Fermentation Research Institute, Agency of Industrial Science and Technology (No. 1-3, Higashi 1-chome, Yatabemachi Tsukuba-gun, Ibaraki Prefecture, Japan) under the deposit number of FERM P-7886 (deposit date: October 5th, 1984), and then convened to Budapest Treaty route of the same depository on Oct. 19, 1985 under the new deposit number of FERM BP-927.

Using the four compounds produced in fermentation above, the remaining compounds of Formula II may be easily produced. The allyl of R⁵ may be conveniently reduced to propyl by well known methods, for example as described in U.S. Pat. No. 4,894,366. The hydroxy of R³ may be protected by well known methods, for example as disclosed in EPO Publication No. 0,323,042. Likewise, the hydroxyl at C-4" may also be protected. In addition, the hydroxy of R³ may be reduced to a hydrogen or eliminated to form a double bond with R⁴ (by methods disclosed in U.S. Pat. No. 4,894,366, EPO Publication No. 0,323,042 or EPO Publication No. 0,413,532). The carbonyl of W may be reduced to the alcohol by methods disclosed in EPO Publication No. 0,323,042 or by methods disclosed in EPO Publication No. 0,445,975.

The methyl of E as produced may be replaced with hydrogen or demethylated and subsequently protected as desired, if necessary. This demethylation of compounds wherein E is methyl may be carried out in a fermentation reaction using the compounds of Formula II as a feedstock. For instance, compound A named under Formula II above may be demethylated at E above by using the microorganism Actinomycetales ATCC No. 53771 (described in U.S. Pat. No. 4,981,792) or by using the microorganism Streptomyces tsukubaensis, No. 9993 (described in EPO. Publication No. 0,353,678). Similarly, compound B named under Formula II above may be demethylated at E above using the microorganism Actinoplanacete sp. ATCC No. 53771 (described in EPO Publication No. 0,349,061). In addition the compound of Formula II wherein E is H, W is O, R³ is hydroxy, R⁴ is hydrogen, R⁵ is ethyl and n is 2 may be produced directly by fermentation using the mutant microorganism Streptomyces hygroscopicus sup. ascomyceticus, No. 53855 (being a blocked mutant of Streptomyces hygroscopicus sup. ascomyceticus, No. 14891) (as described in EPO Publication No. 0,388,152). Similarly, the compound of Formula II wherein E is hydrogen, W is O, R³ is hydroxy, R⁴ is hydrogen, R⁵ is methyl and n is 2 may be produced directly by fermentation using the mutant microorganism Streptomyces hygroscopicus sup. ascomyceticus, No. 53855 (being a blocked mutant of Streptomyces hygroscopicus sup. ascomyceticus, No. 14891 ) (EPO Publication No. 0,388,153). The hydroxy of C-3" may be protected by methods similar to those known for the protection of the hydroxyl groups of R³ and/or C-4", for example as disclosed in U.S. Pat. No. 4,894,366.

Suitable protecting groups for hydroxyl include those groups well known in the an such as: methylthiomethyl, ethylthiomethyl; trisubstituted silyl such as trimethylsilyl, triethylsilyl, tributylsilyl, tri-i-propylsilyl, t-butyldimethylsilyl, tri-t-butylsilyl, methyl-diphenylsilyl, ethyldiphenylsilyl, t-butyldiphenylsilyl, and the like; acyl such as acetyl, pivaloyl benzoyl, 4-methoxybenzoyl, 4-nitrobenzoyl and aliphatic acyl substituted with aromatic group, which are derived from carboxylic acids; and the like.

Compounds A, B, C and D of Formula II, organisms to produce the same, conditions of fermentation, separation techniques, and chemical modification of the products are fully described in U.S. Pat. No. 4,894,366, dated Jan. 16, 1990, U.S. Pat. No. 4,929,611, issued May 29, 1990 and U.S. Pat. No. 5,110,811, issued May 5, 1992.

The novel processes for preparing the novel compounds of the present invention are illustrated as follows, wherein R, R¹, R², R³, R⁵, R⁶, R⁷, R⁸, R⁹, R¹⁰, R¹¹, R¹², R¹³, W and n are as defined above unless otherwise indicated. It will be readily apparent to one of ordinary skill in the an reviewing the synthetic route depicted below that other compounds within Formula I can be synthesized by substitution of appropriate reactants and agents in the synthesis shown below. ##STR17##

Reaction Scheme A:

Protection of the C-3", C-4" and/or the C-14 hydroxyl group(s) may be accomplished by methods known in the art for compounds of Formula II such as by treatment with: 2,6-lutidine and triisopropylsilyl trifluoromethanesulfonate in a solution of methylene chloride; 2,6-lutidine and t-butyldimethylsilyl trifluoromethanesulfonate in a solution of methylene chloride; pyridine and acetic anhydride in a solution of methylene chloride; pyridine and benzoyl chloride in a solution of dichloromethane; pyridine and p-nitrobenzoyl chloride in a solution of dichloromethane; imidazole and t-butyldiphenylsilyl chloride in a solution of methylene chloride; and the like. For example, as shown in Reaction Scheme A, the C-4",14-dihydroxy-C-3"-methoxy macrolide 2 may be protected at C-14 as the t-butyldimethylsilyl ether by treatment with t-butyldimethylsilyl trifluoromethanesulfonate in methylene chloride to give the C-4", 14-di-O-TBDMS macrolide. Treatment with toluenesulfonic acid in methanol results in selective removal of the C-4" silyl ether to give the C-14-O-TBDMS macrolide 3. An alternative method employs 2.5% HF in acetonitrile at 0° C.

Reaction Scheme B:

A key intermediate for the compounds claimed herein is ketone 3 which is easily prepared by oxidation of alcohol 2. A variety of methods may be successfully employed to achieve ketone 3. They include use of the Swern reaction (oxalyl chloride, DMSO and triethylamine (Et₃ N) in methylene chloride). Another reagent that works very well is commonly called the Jones reagent. This is a solution of chromic acid and sulfuric acid in H₂ O.

Reaction Scheme C:

Analogs of 4 may be produced by the use of Grignard reagents (RMgX). A convenient procedure employs a suitable Grignard reagent that is either prepared according to standard procedures or is purchased in the presence of 1 to 2 equivalents of MgBr₂ in ether at low temperatures (-78° C.). When using the MgBr₂ reagent, the configuration of R is the same as R² O--. By this method may be prepared analogs of 4 wherein R can be aryl, heteroaryl, benzyl, allyl, vinyl etc.

Reaction Scheme D:

Olefinations may be achieved at the 4"-ketone group by employing a variety of commonly used methods. The simple methylene analog 5 may be prepared by using trimethylsilyllithium with MgBr₂ etherate. Elimination of the trimethylsilyl group may be achieved by treating the compound with HF in acetonitrile. This also removes the C14-TBDMS group which may be reattached by procedures outlined in Reaction Scheme A. Analogs of 7 may be prepared with phosphorous ylide reagents. In particular, the "Homer-Emmons" or "Wadsworth-Emmons" reagents [(RO)₂ P(O)--CH₂ CCOR'] are particularly effective (for a review, see Organic Reactions 25, 75-253, (1977)).

Reaction Scheme F:

When R⁵ is not allyl, olefinic analogs of 4 such as 4a and 4b, may be selectively converted to aldehydes 8 and 9. For convenience, the 4"-hydroxy group is first protected, in this case as the triethylsilyl (TES) ether by utilizing triethylsilyltriflate (TESOTf) by procedures described in Reaction Scheme A. The olefin is then cleaved by the 2-step oxidiative sequence using catalytic amounts of osmium tetroxide (OsO₄) using N-methyl morpholine N-oxide (NMMO) for regeneration. The resulting glycol is readily cleaved to aldehydes 8 and 9 by standard procedures.

Aldehyde 10 wherein the configuration of the aldehyde group is opposite to that for 9 may be prepared from methylene analog 5 by a multistep approach. Compound 5 is first oxidized to its diol intermediate with osmium tetroxide. The two hydroxy groups are then differentially protected. The primary alcohol may be protected as its trimethylsilyl (TMS) ether using trimethylsilyl chloride (TMS-Cl) and an amine base such as triethylamine. The secondary alcohol may be protected as its TES ether as described above. Next, the primary siloxy group is selectively deprotected with methanol and oxidized to the corresponding aldehyde. For this procedure, the "Swern" procedure may be employed (oxalyl chloride, DMSO, Et₃ N, CH₂ Cl₂). Alternatively, the diol is protected as the bis-TMS ether with trimethylsilyl trifluoromethanesulfonate. Then the primary silyloxy group is selectively deprotected with methanol and oxidized to the aldehyde as shown above.

Reaction Scheme G:

Aldehydes 8, 9 and 10 may be converted to olefins 11, 12 and 13 by any number of well known olefination procedures. Several of these procedures utilize phosphorous ylides including the Wittig reagent (Ph₃ P-CHR'R") which is discussed and referenced in Advanced Organic Chemistry; Reactions, mechanisms and structure, Third edition (author: Jerry March). Another variant of the Wittig reagent (also referenced in the March text) include the Horner-Emmons (also called the Wadsworth-Emmons) reagent (RO)₂ POCHR'R" (also reviewed in Acc. Chem. Research 16, 411-417 (1983)). A third reagent of choice is the Peterson reagent ((CH₃)₂ SiR'Li (reviewed in Accounts of Chemical Research 10, 442-448, (1977)). Following olefination, the protecting groups may be removed by the standard deprotection procedures discussed previously. They include the use of HF in pyridine at reduced temperature.

Reaction Scheme H:

In cases when there are no other competing olefins such as when R⁵ ═allyl, compounds 11, 12 and 13 (protected or unprotected) may be reduced to their saturated analogs 14, 15 and 16 by utilizing any of the many methods of catalytic hydrogenation.

Reaction Schemes I & J:

Aldehydes 8-10 may be oxidized to carboxylic acids 17-19 by any number of methods including use of the Jones reagent as outlined in Reaction Scheme B. Ketone design 17 is also prepared via a condensation reaction between ketone 3 and an enolate anion of an appropriate acetate ester such as the sodium enolate of 2-phenylthioethyl acetate or benzyl acetate (Reaction Scheme J). The resultant esters may be converted to 17 via reaction of HF-pyridine for the phenylthioethyl ester or by hydrogenolysis of the benzyl ester. Other acetate esters are also used as long as the ester may be removed under mild conditions.

Reaction Scheme K:

Carboxylic acids 17-19 are convened to amides and ketones by standard reaction practices. For example, acid 17 is converted to amide 20 by reaction with an appropriate amine and a suitable activating reagent such as dicyclohexylcarbodiimide (DCC) or the water soluble ethyldimethylamino-propylcarbodiimide hydrochloride (EDC, EDAC) in a solvent such as dichloromethane.

Ketone 21 is prepared from 17 via activation of the carboxyl group to an acid chloride (with thionyl chloride) or a mixed anhydride (with an alkylchloroformate such as methylchloroformate in THF with Et₃ N) followed by treatment with a Grignard or other related organometallic reagent.

Reaction Scheme L:

As shown in Reaction Scheme L the 14-hydroxy group of a macrolide (wherein R₁, R₂, R₅, R₁₀, W and n are as defined above) may be eliminated by treatment with p-toluenesulfonic acid, benzenesulfonic acid or methanesulfonic acid in an inert organic solvent such as benzene, or toluene at from 40° C. to 60° C., for about 0.5 to 6 hours, or a sufficient period of time to eliminate the 14-hydroxy group. Neutralization with an aqueous solution of a weak base such as aqueous saturated sodium bicarbonate gives the 14,15-dehydro macrolides 23. The 14-hydroxy group may also be eliminated by activation followed by basic elimination, as described in U.S. Pat. No. 4,894,366.

In cases when there are no other competing olefins present, compound 23 may be reduced to the saturated analog 24 by utilizing any of the many methods of catalytic hydrogenation.

By suitable selection of protecting groups and the sequence of synthetic steps, all possible variations of substitution may be achieved.

Reaction Scheme M:

As shown in Reaction Scheme M, R₂ may be modified in any number of ways utilizing benzyl or alkenyl trichloroacetimidate reagents. When R₂ ═H either as a starting material or after R and R₁ have been prepared and a protecting group R² has been removed, the hydroxy group of 25 may be reacted in an inert organic solvent such as methylene chloride, chloroform, pentane, hexane, cyclohexane, heptane or mixtures thereof with a heteroarylalkyl, heteroarylalkenyl or heteroarylalkynyl trichloroacetimidate reagent (prepared by the reaction of an appropriate sodium alkoxide with trichloroacetonitrile, such as described by Wessel, H. P., Iversen, T., Bundle, D. R:; J. Chem, Soc., Perkin Trans. I, 1985, 2247) in the presence of a mild acid catalyst such as trifluoro-methanesulfonic acid, p-toluenesulfonic acid, methanesulfonic acid, or mixtures thereof at a temperature of 20°-50° C. for a period of from one hour to seven days to give the 4"-O-heteroarylalkyl-, 4"-O-heteroarylalkenyl- or 4"-O-heteroarylalkynyl-3"-methoxy macrolide 26.

Alternatively, aryl or heteroaryl ether derivatives of R² may be prepared. A solution of 25 in an inert organic solvent such as methylene chloride, benzene, toluene, chloroform, or the like or mixtures thereof is treated with a triaryl- or triheteroarylbismuth diacetate reagent (prepared immediately prior to use by the addition of acetic acid to a suspension of a triaryl- or triheteroarylbismuth carbonate in an inert organic solvent such as methylene chloride, choroform or the like or mixture thereof) in the presence of a catalytic amount of copper(II) acetate at a temperature of 20°-50° C., preferably room temperature, for a period of one hour to seven days, preferably one day, to give 27. Alternatively, the triaryl- or triheteroarylbismuth(V) reagent may be prepared by treatment of a triaryl- or triheteroarylbismuthine with a suitable oxidant such as peracetic acid, iodobenzene diacetate, bis(trifluoroacetoxy) iodobenzene and the like in an inert solvent such as methylene chloride, chloroform, benzene, toluene and the like. The triaryl- or triheteroarylbismuth(V) reagent may be used without purification or may be purified by silica gel chromatography. Triaryl- or triheteroarylbismuthines may be prepared by the reaction of an appropriate aryl or heteroaryl grignard reagent with bismuth trichloride in an inert organic solvent such as tetrahydrofuran, diethyl ether, or 1,4-dioxane, or mixtures thereof, at or near room temperature for a period of 1 to 48 hours. General procedures for the preparation and use of triheteroaryl bismuth reagents may be found in Barton, D.H.E., et al., J., Chem. Soc. Chem. Commun., 65, 1986 and references cited therein.

Reaction Scheme N:

A hydroxyl or fluoro group may be introduced at C-20 essentially by the procedures of Reaction Scheme N. The suitably protected macrolide 28 is oxidized at C-20 by treatment with selenium dioxide in an alcoholic solvent such as ethanol in the presence of pyridine at solvent reflux temperature to give the 20-hydroxy macrolide (29). The 20-hydroxy macrolide may be further derivatized at C-20 by alkylation, acylation or phosphorylation to give ether, ester or phosphate derivatives by procedures well known to the practitioner of the art. As further illustrated, treatment of the 20-hydroxy macrolide 29 with diethylaminosulfur trifluoride in an inert organic solvent such as methylene chloride, chloroform or the like at a temperature of about 0° C. to -90° C., preferably about -78° C., gives the 20-fluoro 4", 14-di-OTBS macrolide (30). The procedures of Reaction Scheme J may be conducted prior to, concurrent with, or subsequent to the procedures of Reaction Schemes A-M.

Reaction Scheme O:

Suitably modified and protected compound 31 may be modified in the tricarbonyl region. Keto group at the 2-position may be selectively reduced using several procedures. Reaction of compound 31 with sodium borohydride (NaBH₄) in isopropanol at reduced temperatures may provide compound 32.Alternatively, Samarium iodide (SmI₂) in THF and methanol at -78° C. with slow warming to rt is also effective.

C₂ -hydroxy analog 32 may be converted to methylene derivative 33 a two-step sequence. The first step requires activation by use of methanesulfonyl anhydride, for example, to give the methanesulfonate ester. This may be carried out in pyridine. The second step requires reaction with a mercaptan reagent such as paramethoxybenzylmercaptan (PMB-SH) in a solvent such as DMF with Et₃ N in an oxygenated atmosphere. This reaction sequence may be accomplished in good yield.

The procedures of Reaction Scheme O may be conducted prior to, concurrent with, or subsequent to the procedures of Reaction Schemes A-N.

Reaction Scheme P:

The C-1 hydroxy group of compound 34 may be removed by dehydration using triphenylphosphine (Ph₃ P) and diethylazodicarboxylate (DEAD) in THF at reduced temperatures to provide dehydro derivative 35.

Compound 35 may be selectively reduced to saturated analog 36 by conjugate reduction. One reagent that is particularly effective is potassium triphenylborohydride (KHBPh₃) in THF at -78° C.

The procedures of Reaction Scheme P may be conducted prior to, concurrent with, or subsequent to the procedures of Reaction Schemes A-N.

Reaction Scheme O

Carbanions may be added to the aldehyde to afford the corresponding alcohol. A convenient procedure employs a suitable Grignard reagent that is either prepared according to standard procedures or is purchased in the presence of 1 to 2 equivalents of MgBr2 in ether or tetrahydrofuran at low temperatures (-78° C. to -20° C.). Under these conditions, both diastereomers at the new center are obtained. Following addition, the silyl groups may be removed by treatment with 5-10% HF in acetonitrile as described above.

Reaction Scheme R

Titanium reagents may be added to the aldehyde to afford the corresponding alcohol. A convenient procedure employs a suitable titanium reagent that is prepared via transmetallation of an alkyllithium or Grignard reagent with chlorotitanium triisopropoxide. The titanium reagent is added to the aldehyde in ether or tetrahydrofuran at low temperatures (-78° C. to -20° C.). Under these conditions, both diastereomers at the new center are obtained. Following addition, the silyl groups may be removed by treatment with 5-10% HF in acetonitrile as described above.

Reaction Scheme S

The tetrahydrofuran analog may be obtained via cyclization of the hydroxypropyl analog under strong Lewis acid condition, such as 20% HF in acetonitrile or HF-pyridine over several days. This step also deprotects the 24-silyl group.

The object compounds of Formula I obtained according to the reactions as explained above can be isolated and purified in a conventional manner, for example, extraction, precipitation, fractional crystallization, recrystallization, chromatography, and the like.

It is to be noted that in the aforementioned reactions and the post-treatment of the reaction mixture therein, the stereoisomer(s) of starting and object compounds due to asymmetric carbon atom(s) or double bond(s) of the object compounds of Formula I may occasionally be transformed into the other stereo isomer(s), and such cases are also included within the scope of the present invention.

In the present invention, compounds with asymmetric centers may occur as racemates, as diastereomeric mixtures and as individual diastereomers, with all isomeric forms of the compounds being included in the present invention. These may be prepared by methods such as those disclosed in publications which describe synthetic routes to fragments of the macrolide FR-900506 and the total synthesis of the macrolide FR-900506 itself (J.

The pharmaceutical compositions of this invention can be used in the form of a pharmaceutical preparation, for example, in solid, semisolid or liquid form, which contains one or more of the compounds of the present invention, as an active ingredient, in admixture with an organic or inorganic carrier or excipient suitable for external, enteral or parenteral applications. The active ingredient may be compounded, for example, with the usual non- toxic, pharmaceutically acceptable carriers for tablets, pellets, capsules, suppositories, solutions, emulsions, suspensions, and any other form suitable for use. The carriers which can be used are water, glucose, lactose, gum acacia, gelatin, mannitol, starch paste, magnesium trisilicate, talc, corn starch, keratin, colloidal silica, potato starch, urea and other carriers suitable for use in manufacturing preparations, in solid, semisolid, or liquid form, and in addition auxiliary, stabilizing, thickening and coloring agents and perfumes may be used. For example, the compounds of Formula I may be utilized with hydroxypropyl methylcellulose essentially as described in U.S. Pat. No. 4,916,138, issued Apr. 10, 1990, or with a surfactant essentially as described in EPO Publication 0,428,169. Oral dosage forms may be prepared essentially as described by T. Hondo, et al., Transplantation Proceedings, 1987, XIX, Supp. 6, 17-22. Dosage forms for external application may be prepared essentially as described in EPO Publication 0,423,7 14. The active object compound is included in the pharmaceutical composition in an amount sufficient to produce the desired effect upon the process or condition of diseases.

For the treatment of these conditions and diseases caused by immmunoirregularity a compound of Formula I may be administered orally, topically, parenterally, by inhalation spray or rectally in dosage unit formulations containing conventional non-toxic pharmaceutically acceptable carriers, adjuvants and vehicles. The term parenteral as used herein includes subcutaneous injections, intravenous, intramuscular, intrasternal injection or infusion techniques.

For the treatment of reversible obstructive airways disease, it is preferable that the compound of Formula I be administered by inhalation to the lung, especially in the form of a powder.

For modifying the activity and/or toxicity of FK-506-type immunosuppressants, a compound of Formula I may be administered prior to, in conjuction with or subsequent to the administration of an FK-506-type of a compound.

The compounds of Formula I may optionally be employed in co-therapy with anti-proliferative agents. Particularly preferred is co-therapy with an antiproliferative agent selected from the group consisting of azathioprine (AZA), brequinar sodium, deoxyspergualin (DSG), mizaribine, mycophenolic acid morpholino ester (RS-61443), cyclosporin and rapamycin.

The compounds of Formula I may also be employed in conjunction with (or in a pharmaceutical composition additionally comprising):

(1) a 5α-reductase inhibitor,

(2) a cyclosporin,

(3) a potassium channel opener (such as minoxidil), or

(4) a phospholipid.

Such co-therapy is particularly useful in hair revitalizing, such as in the treatment of male pattern alopecia, female pattern alopecia, alopecia senilis or alopecia areata, by providing epilation prevention, hair germination, and/or a promotion of hair generation and hair growth.

Such co-therapy is further useful in treating the hyperandrogenic conditions of androgenic alopecia, acne vulgaris, seborrhea, and female hirsutism.

For co-therapy of these conditions and diseases a compound of Formula I may be administered in combination with prior to, concurrent to, or subsequent to the administration of other agent(s).

For hair revitalizing the compound of Formula I may be administered topically or orally. Cyclosporin may be administered topically or orally. Although the 5α-reductase inhibitor or the potassium channel opener may be administered topically or orally, it is preferable that it be administered topically to the scalp. For unitary formulation, however, the preferred mode of administration is topically. It is especially preferred that the hair revitalizing composition of the present invention is administered by a percutaneous administration or by spraying onto the skin.

Dosage levels of the compounds of the present invention are of the order from about 0.005 mg to about 50 mg per kilogram of body weight per day, preferably from about 0.1 mg to about 10 mg per kilogram of body weight per day, are useful in the treatment of the above-indicated conditions (from about 0.7 mg to about 3.5 mg per patient per day, assuming a 70 kg patient). In addition, the compounds of the present invention may be administered on an intermittent basis; i.e. at daily, semiweekly, weekly, semi-monthly or monthly intervals.

The amount of active ingredient that may be combined with the carrier materials to produce a single dosage form will vary depending upon the host treated and the particular mode of administration. For example, a formulation intended for the oral administration of humans may contain from 0.5 mg to 5 gm of active agent compounded with an appropriate and convenient amount of carrier material which may vary from about 5 to about 95 percent of the total composition. Dosage unit forms will generally comprise from about 0.01 mg to about 500 mg, and preferably about 0.5 mg to about 100 mg of active ingredient. For external administration the compound of Formula I may be formulated within the range of, for example, 0.0001% to 60% by weight, preferably from 0.001 to 10% by weight, and most preferably from about 0.005 to 0.8% by weight.

It will be understood, however, that the specific dose level for any particular patient will depend on a variety of factors including the activity of the specific compound employed, the age, body weight, general health, sex, diet, time of administration, route of administration, rate of excretion, drug combination and the severity of the particular disease undergoing therapy.

The following examples are given for the purpose of illustrating the present invention and shall not be construed as being limitations on the scope or spirit of the instant invention.

EXAMPLE 63 T-Cell Proliferation Assay

1. Sample Preparation

The compounds to be assayed were dissolved in absolute ethanol at 1 mg/ml.

2. Assay

Spleens from C57B1/6 mice were taken under sterile conditions and gently dissociated in ice-cold RPMI 1640 culture medium (GIBC), Grand Island, N.Y.) supplemented with 10% heat-inactivated fetal calf serum (GIBO)). Cells were pelleted by centrifugation at 1500 rpm for 8 minutes. Contaminating red cells were removed by treating the pellet with ammonium chloride lysing buffer (GIBO)) for 2 minutes at 4° C. Cold medium was added and cells were again centrifuged at 150 rpm for 8 minutes. T lymphocytes were then isolated by separation of the cell suspension on nylon wool columns as follows: Nylon wool columns were prepared by packing approximately 4 grams of washed and dried nylon wool into 20 ml plastic syringes. The columns were sterilized by autoclaving at 25° F. for 30 minutes. Nylon wool columns were wetted with warm (37° C.) culture medium and rinsed with the same medium. Washed spleen cells resuspended in warm medium were slowly applied to the nylon wool. The columns were then incubated in an upright position at 37° C. for 1 hour. Non-adherent T lymphocytes were eluted from the columns with warm culture medium and the cell suspensions were spun as above.

Purified T lymphocytes were resuspended at 2.5×10⁵ cells/ml in complete culture medium composed of RPMI 1640 medium with 10% heat-inactivated fetal calf serum, 100 mM glutamine, 1 mM sodium pyruvate, 2×10-⁵ M 2-mercaptoethanol and 50 μg/ml gentamycin. Ionomycin was added at 250 ng/ml and PMA at 10 ng/ml. The cell suspension was immediately distributed into 96 well flat-bottom microculture plates (Costar) at 200 μl/well. The various dilutions of the compound to be tested were then added in triplicate wells at 20 μl/well. The compound 17-allyl-1,14-dihydroxy-12-[2'-(4"-hydroxy-3"-methoxycyclohexyl)-1'-methylvinyl]-23,25-dimethoxy-13,19,21,27-tetramethyl-11,28-dioxa-4-azatricyclo[22.3.1.0⁴,9 ]octacos-18-ene-2,3,10,16-tetraone was used as a standard. The culture plates were then incubated at 37° C. in a humidified atmosphere of 5% CO₂ -95% air for 44 hours. The proliferation of T lymphocytes was assessed by measurement of tritiated thymidine incorporation. After 44 hours of culturing, the cells were pulse-labelled with 2 μCi/well of tritiated thymidine (NEN, Cambridge, Mass.). After another 4 hours of incubation, cultures were harvested on glass fiber filters using a multiple sample harvester. Radioactivity of filter discs corresponding to individual wells was measured by standard liquid scintillation counting methods (Betacounter). Mean counts per minute of replicate wells were calculated and the results expressed as concentration of compound required to inhibit tritiated thymidine uptake of T-cells by 50%.

A selection of compounds were tested according to the previous procedure. The title compounds of the following Examples had activity in inhibiting the proliferation of T-cells in the aforementioned assay:
